I bought a pair on ebay for 269 + 34 shipping by DHL air into Canada. I'm expecting them today. Will let you know how much the surcharges are. Either way, it's much better than the retail cost here in Canada; but that's been well documented and bemoaned elsewhere on head-fi.
Other ebay sellers were selling for less, but these were shipping to Canada by UPS ground. For us Canucks the biggest problem is the exorbitant "brokerage fee" charged by couriers like UPS or FedEx when they deliver by "standard" or "ground" services. It can be quite a shock; afew years back I paid about $120 on top of a $300 used synthesizer. Supposedly air service does away with brokerage fees. And US postal service is the probably the most cost-efficient all-round.
Anyway, once the buyer knows what to expect, the buyer can factor these things into the calculation. This time around, for me, purchasing the K701s via ebay should be worthwhile, regardless of brokerage.
While I'm ranting (sorry), it's a shame that most US sellers on this site do not ship north to Canada. :-(
